Möglicherweise liege ich ja falsch, aber so was gibt es doch schon in Form von http://www.geonames.org/

GeoNames is only for location and not for address.
OpenAddresses aim to be complimentary with GeoNames and OpenStreetMap

Well, I like the map of OpenAddresses.org.
But have you tried to enter an address at GeoNames and searchor show it on the map (as for bahnhofstrasse 35, zürich)

You will see:
1 Bahnhofstrasse 35
8001 Zurich47.3712048.538616 Switzerland, CH.Switzerland N 47° 22' 16'' E 8° 32' 19''

So where is the difference to OpenAddress?
